MACHINE FOR FINISHING GLASSWARE.

To all wiwm it may concern:

Be it known that we, AND EW J. SANFORD and JOHN B. TOWNSEND, citizens of the United States, and residents of Newark, in

position; and Fig. 4 is a plan view of the entlre machine.

Figs. 1 and 4 show a machine which consists of a rotary carrier that rotates in a 5 the county of Licking and State of Ohio, step-by-step manner and'carries a series of have invented-a new and useful Improvement in Machines for Finishing Glassware; and we do hereby declare the following to be a full, clear, and exact description thereof.

Our invention relates to glass finishing machines having snap devices for holding the glassware during the fire-polishing and finishing operations, vide an automatic finishingmachine having a simple and effective snap which shall op crate automatically to receive the ware to be finished, to carry the Ware through the finishing operations, and finally to discharge the finished ware. I

Our copending application for Letters Patent filed August 30, 1921, Serial No. 496,884, describes and claims a machine for receiving tumblers, nappies and other hollow lassware, carryingthe ware to a series of re-polishing glory holes, with exposure to the air between the fire-polishing operations,

then finishing and burnishing the firepolished ware, and finally discharging the finished ware. The said copending applica' tion shows, as its specific means for holding and conveying the ware, a form of device in which the ware is stuck up upon the lower surfaces of ware holding punties and is attached to the punties by the adhesion of the soft glass. Our present invention is designed to provide a machine of the same character as that of the said copending application, and having a snapping-up device for holding and conveying the ware. It will be understood, however, that certain features ofour present device may be employed with other forms of machines for handling glassware.

In the accompanying drawings, Fig. 1 a side elevational view showing so much of a fire-polishing and finishing machine as is necessary to an understanding of the present and its object is to pro- S12: vertical punty devices, each of which is provided with a snap device for grasping and holding the glassware. The carrier is caused to advance one-sixth of a revolution at each step. At the first position the ware is snapped up and attached to the puntyyat the second position it enters the first glory hole; at the third and fourth positions it enters the second and third glory holes; at the'fifth position it is finished; and at the sixth position it is released from the snap.

The frame of the machine consists of a base plate 1, a center plate 2, and a top plate 3, the center and top plates being separated from the base plate by means of columns 4 which are mainly omitted from the drawing for the sake of clearness. The entire machine may be carried on suitable wheels 5.

For the purpose' 'of conveying the ware to the several operating positions successively, a set of six snap device's, indicated generally by the numeral 6, is suspended from a plate 7 which is given a step-by-step rotation.

Power for operating the machine is derived from a motor 8, the shaft of which carries a pinion 9 meshing with a gear 10 on a countershaft 11 to which is secured a worm 12 meshing with a worm wheel 13 on a vertical power shaft 14. The base plate 1 also carries gearing for raising and lowering a glory hole furnace 32,-but as this mechanism is not necessary for a description of my present invention it is omitted from the drawing.

For the purpose of bringing the ware into position to be received by the snaps, we pro vide a device which is similar to that shown in .our above-mentioned application, and

which consists of a head carried at the upper end of a rod 41 which extends through oted on a bracket 43 secured to the under side of the center plate 2. One end of the lever 42 carries a cam roller 44 which engages a cam 45 secured to the vertical power shaft 14. The other end of the lever 42 is slotted at 46 to receive a pin 47 carried at the upper end of a vertical link 48, the lower end of which is adjustably connected to the rod 41. The head 40 carries a flanged plate 49 on which is shown a nappy N in position to be raised into engagement with the snap.

Before proceeding to a detailed description of the snap device, it may be stated that all of these devices are given an intermittent rotation in the glory hole and finishing positions by means of bevel gear wheels 208on horizontal shafts 209 which are secured in bearings 210 on the rotating plate 7 which rests on ball bearings ,215 in a suitable ball race on the stationary plate 3. Each shaft 209 carries two friction wheels 211 which are feathered on the shaft 209 and may be adjusted lengthwise of this shaft by means of forks 212 carried by a rod 213 that extends through thebearings 210. A friction wheel 220 is keyed to a central shaft 217 which is oscillated back and forth by means of a lever 221 which has one end secured to the oscillating central shaft 217 while its other end is attached by a pin and slot connection to one end of a pitman 222. The other end of the pitman 222 is pivoted on the under side of a crank wheel 223 mounted on a pin 224 which hangs from the under side of the stationary top plate 3. A gear 225 is formed integral with or secured to the crank wheel 223, and meshes with a gear 228 on the main vertical power shaft 14.

The parts thus far described are similar to those described in our said prior application, and it is believed that they are suflicient to show the general manner in which the ware is handled. For convenient reference, we have employed the same reference numerals as in the said application to indicate the various parts referred to above.

Proceeding now to a description of the snap device, and with particular reference to Figures 2 and 3, each of these devices consists of a tubular punty 100 which is secured in a chuck 101 of ordinary construction and carries at its lower end a snap consisting of a hollow circular head 102 having a collar 103 which is rigidly attached to the lower end of the punty tube 100, and having an inner flange 104 formed around its lower open end. Three or more movable'gripping fingers 105 are'suspended from the flange 104 and'are' provided with projections 106 which are received in. a circular recess formed around the lower end 107 of an operating rod 108. The fingers 105l1ave ware-holding hooks 109 at their lower ends and are loose I in the member 102, being prevented from falling out by engagement of their projections 106 with the rod 108 and the flange 104. The rod 108 also carries a circular flange 110 above its flaring lower end 107. By the construction just described the rod 108, when moved-lengthwise in the tube 100, operates the ware-holding fingers 105. When the rod 108 is raised, as shown in Fig. 2, the lower projection 107 engages the projections 106 of the fingers 105 and forces them all into their ware-holding position.- When,

however, the rod 108 is moved down in the tube 100,the flange 110 depresses the projections 106 of the fingers 105 and thereby moves the fingers to their inclined position shown in Fig. 3.

The punty tube 100 has a reduced portion 112 which serves as a seat for the lower end of a spring 113 which surrounds the rod 108 and is confined between the seat 112 and the lower end of a sleeve 114 which is attached to the upper end of the rod 108 by means of a pin or rivet 111. The chuck 101 is secured to the lower end of a hollow shaft 115 mounted in ball bearings 116 in a support 117 which is suspended in an opening in the plate 7 by means of a circular flange 118. A sleeve 119 is keyed to the upper end of the hollow shaft 115 and carries a bevel pinion 120 meshing with the bevel gear 208 on the shaft 209 as described above. The hollow shaft 115 contains an opening 121 of relatively large diameter for receiving the upper end of the tube 100, and also contains an opening 122 of less diameter through which extends a rod 123 which rests upon the upper end of the operating rod 108. The rod 123 carries a striking block 125 which is adj ustably secured to the rod 123 by means of a set screw 126.

It will be observed that if the rod 123 is depressed it will force down the operating rod 108 and will compress the spring 113, and that the downward movement of the rod 108 will open the snap as described above. Also, it will be seen that when pressure on the rod 123 is released the spring 113 will return the rods 108 and 123 to their upper position as in Fig. 2, which will close the snap in the manner described. For the purpose of actuating the rod 123 at the snapping-up position and at the ware detaching position we provide a cam 130 which is keyed to the main vertical power shaft 14, and which has a cam surface 131 extending around its upper edge. A cam roller 132 runs upon the cam surface 131 and is secured at one end of a lever 133 secured to a rock shaft 134 which is carried in brackets 135 which depend from the underside of the stationary top plate 3. The rock shaft 134 also carries two striking arms 136 and 137. The striking arm 136 operates the snap which is at the snapping-up or ware attaching position, and the arm 137 operates the snap which is at the ware detaching position. Both of these operations take place by the engagement of the outer ends of the arms 136 and 137 with projections 138 on collars 139 secured to the lower ends of vertical y 142 carried by the rotating plate 7 and car tlOll releases the finished article ries rigidly at its upper end a sleeve 143 having an arm 144 which has an opening to receive theupper end of the rod 123. The striking block 125 which is carried by the rod 123 is so adjusted that when the rod 140 is moved down the arm 144 strikes the block 125 before the rod 140 completes its downward movement and thereby pushes down the rods 123 and 108 to open the snap. A spring 145 surrounds the rod 140 L within the bearing 142 and acts to return the rod 140 and the arm 144 to their up or position as soon as the rod is release striking arm 136 or 137.

A weight 146 is secured to the arm 133 in order to keep the roller 132 in engagement with the cam surface 131 of the cam 130.

Fig. 2 shows two of the snap devices, one in section and the other in elevation. The device in sect-ion is at the ware attaching position, and the device in elevation is at the ware discharging position, where it happens to be directly behind the rod 140 which is at its discharge position. To avoid confusion it should be noted that the rod 140 shown in Fig. 2 is not associated with the ware holder directly behind it, but with the ware holder shown at its right at the side of this figure.

In the operation of the snap device described above, the shaft 14 rotates once for each forward step of the machine, and in so rotating carries with it the cam 130 which operates through the roller 132 and the arm 133 to rock the shaft 134 during the interval between the step-by-step movements of the plate 7 which carries the ware holders. This movement of the rock shaft 134 causes the striking arms 136 and 137 to engage the projections 138 associated with the ware holders which, at the moment, are in the ware attaching and ware detaching positions, and draws down the two arms 140 at the attaching and detaching positions, thereby causing the arms 144 to strike the block 125 and lower the rods 123 and 108. The fingers 105 are thereby moved from the closed position of Fig. 2 to the open position of Fig. 3. At this time the cam operates through the connections described to raise the head 40 and place the nappy N in position with its flange ready to be gripped by the fingers 105'. At the same time the openlng of the snap at the discharge iby the been brought to that position, and'this article is removed by any suitable means. The

continued rotation of the cam raises the striking arms 136 and springs 145 raise the rods 140 the blocks 125, whereupon the 130 quickly 137, and the and release which has springs 113 raise the rods 108 and close the fingers 105 upon the nappy which has been placed in the attaching position, as stated above. At the same time the fingers 105 of the snap at the discharge position are also closed. These operations are repeated in each interval between the step-by-step movement of the ware holders.

We have shown in the accompanying drawing the form in which we now' prefer to construct our invention, but it is to be understood that various changes in the ar rangement and construction of parts may be made without departing from our invention, which is limited only by the scope of the appended claims.
